Poor Quality Of Instruction Leads To Poor Motor Performance Regardless Of Internal Or External Focus Of Attention, M. Jay Polsgrove, Tom E. Parry, Nathan T. Brown

International Journal of Exercise Science

International Journal of Exercise Science 9(2): 214-222, 2016. The view that external focus of attention provides beneficial performance outcomes when compared to an internal focus of attention has been consistently supported in the movement performance literature. While type of focus has been well investigated, the current study examined the influence of quality of instruction as a variation of the type of focus. Specifically, the purpose of the study investigated how performance-enhancing instructions would differ from performance-neutral instructions on an agility performance. An agility L-run was used to measure performance in the four counterbalanced conditions: Internal-Performance Neutral (INT-PN), Internal-Performance Enhancing (INT-PE), …

Failures In Adaptive Locomotion In Healthy Young Adults, Michel J. H. Heijnen

Open Access Dissertations

Young adults fall most frequently when walking, and trips account for 25% of these falls (Heijnen & Rietdyk, 2016). Common approaches to understanding tripping include the examination of behavior when a stationary obstacle is crossed successfully, or to deliberately trip the participant with a covert obstacle. However, these approaches do not establish the underlying cause of failure; examining inadvertent failures does, as this occurs most often in the field (Heijnen & Rietdyk, 2016). In order to identify the behavior that results in obstacle contact, this dissertation examined gait characteristics during inadvertent failures and manipulated the sensory information available to guide …

Ingestion Of A Nutritional Supplement Pre-Workout Will Increase Exercise Time-To-Fatigue, Allison D. Bloomer, Beena R. Chemmanchery, Rachel Liebowitz, Hannah M. Zalaker

Kinesiology 288

Everyone fatigues at the end of an intense exercise bout. However, previous research has indicated that ingestion of a mixed nutrient supplement one hour pre-exercise will increase exercise time-to-fatigue¹. For this experiment, four females between the ages 20-50 participated in a controlled pilot study. Exercise was performed using a row machine, where time- to-fatigue was measured from a baseline of 80% max HR (220 minus age). The nutrient supplement was ingested 1 hour pre-rowing and contained 30g of protein, 5g carbohydrate, and 3g of fat. Results showed that pre-exercise ingestion of a mixed protein supplement did increase row time-to-fatigue.

Blood Glucose Levels And High Intensity Exercise With Respect To Meal Timing, Gabriel S. Barnett, Bryan A. Frees

Kinesiology 288

The research conducted was about monitoring blood glucose levels with exercise with respect to meal timing. It has been hypothesized that with short bouts of high intensity exercise, one can raise their blood glucose levels because in acute response to high intensity exercise. Previous research has shown that with long bouts of exercise while fasting you can lower blood glucose levels. This study is testing the meal timing from fasting to right before the exercise and also eating one and two hours before combined with a 50 minute moderate to high intensity workout, keeping the heart rate in zones 3- …
